Title: Improvements relating to the mounting of engine fly wheels
IPC: F16F15/126
Filed: 1927-05-17
Abstract: 295,959. Edge, S. r., and Smith, S. May 17, 1927. Flywheels. - In mechanism wherein the engine drive is transmitted to the transmission mechanism through the flywheel and a clutch or the like, the flywheel is flexibly connected to the engine shaft to reduce vibrations. The flexible connection may comprise rubber buffers or discs, fabric discs, springs, resilient metal discs, or combinations of these. In Fig. 1, the flywheel 3 has a perforated flange 9 and is slidably mounted on a flange 2 secured to the crank shaft 1 and is resiliently bolted thereto by a rubber and fabric disc 4. A plate 7 engaging the outer face 8 of the flywheel controls lateral movement. Distance pieces are shown at 11. In the modification Fig. 4, concentric rings 15 and elastic buffers 14 are arranged around the bolts 6. To prevent the soft, rubbing, metal surfaces seizing, the parts may be separated by thin plates of spring steel 17, 18, or ball or roller bearings. The plates may be arranged to exert spring pressure between the parts. The elastic buffers 14 may take the form of spiral springs. In a further modification, an annular ring is interposed between the flange 2 and the flywheel 3 to bring the elastic buffers into a more accessible position. The ring carries studs or bolts located in holes in an internal flange of the flywheel, or vice versa. Rubber or spring buffers are arranged around the bolts the shanks of which are provided with spring, steel discs which put a lateral load on the flywheel when the bolts are tightened. In a further modification flanged sleeves are interposed between the buffers and the wheel 3 to limit the area of contact.

Title: Sliver balling head mechanism
IPC: D01G27/00
Filed: 1960-04-14
Abstract: 917,072. Sliver-winding apparatus. WARNER & SWASEY CO. April 14, 1960 [June 22, 1959], No. 13334/60. Class 120 (1). Mechanism for winding a sliver ball has compensating means to maintain constant the length of sliver between its delivery point and a wind-up arbor on to which the sliver is guided by a reciprocatory cross-head. Reciprocation of the crosshead 39 is effected by a transverse gear 76 through an arm 42 that carries on a pivot shaft a slotted drive yoke 85 actuated by a roller 92 adjustably carried by the traverse gear 76. By means of a lug 87 and pivoted link 89, the drive yoke 85 maintains its initial orientation during oscillation of the arm 42. In order to reciprocate the cross-head 39 at a nearly uniform velocity, the speed of the traverse gear 76 is varied in a similar manner to that described in Specification 821,184 by transmitting drive to the gear 76 through a crank 59, roller 60 and yoke 62, Fig. 2. In its passage to the arbor 34, the sliver 132 extends over a guide 123 and through a trumpet 113 that is reciprocated with the crosshead 39 and rotated in opposite directions with changes of crosshead direction by means of a pinion 118, Fig. 6, carried by the trumpet 113 which meshes with rack teeth on a crosshead guide rail 40. The sliver guide 123 is carried on a compensating arm 120 pivoted at 121 and carrying a pair of arms 124 to which is attached a cam follower bar 125 that is pressed by a spring 130 against a conical roller 127 carried by the arm 42. As the traverse arm 42 approaches the ends of its stroke, roller 127 moves away from the crosshead 39 on which the arm 120 is pivoted and the sliver guide 123 moves closer to the trumpet mouth 113, thus compensating for the increased distance of the trumpet 112 from the sliver delivery point at the rollers 18, 20.

Filed: 1919-05-28
Abstract: 154,948. Clayton, J. May 28, 1919. Lift valves; closure members, lift; casings.-Relates to screw-and-gearing actuated lift valves of the type in which the valve member moves in the casing co-axially with the fluid flow and at right-angles to the operating- spindle to which it is geared. In the present arrangement, a collar q on the inner end of the operating-spindle p co-operates with the stuffing-box s to form a tight joint round the spindle. The valve member and its actuating screw-and-bevel gear h, o and spindle p may be carried by a removable cover 6 of the casing a, as shown. In a modification, however, these parts are mounted integrally with the casing. The screw spindle h is made detachable by means of a removable collar 3 thereon, this collar being covered by a plate, or by a cap 4 enclosing a. spring 12 which allows for expansion and contraction of the valve parts. The valve may be fitted with a renewable facing secured by a clamping-plate and a screw-and-nut connexion. Fig. 8 shows a facing 20 secured by a central stud and nut and having spherical surfaces 21, 30, as shown, to allow of self-adjustment in seating. The periphery is formed with bevel teeth 25 gearing with a pinion 26 fitted with a hand-wheel 28 so that the valve facing can be adjusted circumferentially when required to ensure even wear.

Title: Preparation of dimethyl terephthalate
IPC: C07C69/82
Filed: 1956-05-02
Abstract: The invention comprises a process for the preparation of dimethyl terephthalate by reacting methanol with terephthalic acid in the presence of a weak esterification catalyst to give about 88-92% conversion to the dimethyl ester, cooling the esterification reaction mixture to crystallize crude dimethyl terephthalate, separating the latter from the liquid portion of the reaction mixture, and then fractionally distilling it, to obtain dimethyl terephthalate of high purity as a heart cut.  Any partially esterified terephthalic acid remaining in the mother liquor may be further reacted with methanol in a similar manner. The crystallized material may be washed with methanol and/or further recrystallized from a hydrocarbon solvent, e.g. para-xylene, benzene, alkybenzenes and paraffins.  The final product may also be recrystallized from methanol.  Any of the mother liquors may be recycled.  Catalysts specified are zinc oxide or mixtures thereof with zinc dust and oxides of aluminium, lead, magnesium, and calcium, finely divided tin, manganese, bismuth, lead, silver, and copper, aluminium, cobalt, lead, magnesium, tin and manganese stearates, or amine resins.  The reaction may be carried out at 185-210 DEG  C. at 400-850 p.s.i.g. and the ratio of methanol to terephthalic acid is preferably 3-20 : 1.  The catalyst concentration is preferably about 0.1-5 parts by weight (calculated as zinc oxide) per 100 parts of terephthalic acid.  The process may be carried out batchwise, continuously or intermittently.  Examples are given.
